Solve basic auth proxy issues with Nuget, Visual Studio and Xamarin (hack)
You’ll get the following error:
[5:06] Download failed. Please download https://dl-ssl.google.com/android/repository/android_m2repository_r29.zip and put it to the C:UsersuserAppDataLocalXamarinXamarin.Android.Support.Design220.127.116.11 directory.<br />[5:06] <b>Reason: The remote server returned an error: (407) Proxy Authentication Required.</b><br />
I’ve come to rely on my trusted hacking friend Fiddler and turn on “Automatically Authenticate”.
Optionally configure your upstream proxy in Fiddler:
Restart Visual Studio so it picks up Fiddler as the proxy and you’re good to go. Just leave Fiddler running in the background and all will be well.
